To all whom t mayA concern:

Be it known that I, BERNAnn Moscoviroii, a citizenAoffthe/Kingdm off Bulgaria, residing at Rodenkirchen-Cologne, Germany,

Blucherstrasse 12, have invented new and nipulation, and which are particularly` useful Improvements'in Tar Separators, ofV

which the following is a specification.

This invention has reference to tar separators lof Vimproved constructoir and maadapted for the purification of producers, and it is an important o jee this invention to effect a perfect purification of the gas produced, so that the gas is delivld to the point of consumption or operation,

a suction-,gas-engine for instance, in a conditlon 1n wh1ch\the\tar contentsliave benentirely remoyed. By'the tar separating means according trthis invention it becomes possible to employ any kind of low grade fuel,

such as lignite, brown coal or the like for the feeding of producers and the like which heretofore could only be operated by employing anthracite and other high grade coal.

` This object is accomplished by causing the gas issuing from the producer, after having been freed in any suitable manner from the bulk of dust and ashes, to pass through the tar eliminating means where itis most vigorously mixed by movable and stationary means in such a manner that a complete separation of tar is produced. Upon its introduction -into the 'purifying-'means the gas is submitted to the action .of a suitable chemical compound adapted to roduce a very thorough` preliminary puri cation of the gas. The movable means referred to may comprise vanes and bell-shaped structures mountedupon a common shaft. The vanes, blades or the like are'a.dapted to be moved within grate shaped structures 'in such a manner that a frequent and sudden change of direction is imparted to the gas, whereby the separation of tar is induced. Provision may also' be made in the interior of the tar separator of a sprinkler or shower apparatus which removes the last traces of tar and at the same time effects the cooling of the gas. l

The eliminated tar settles tothe bottom,v

and accumulates in a collecting vessel provided fortlle purpose fromwhich it may be run'vl oili according to requirements. Any

sparrtus is shown by way o e gas from of tlprm'ciples of the invention, Without,'5\r

A partition 4 forms a passage 5 for the introduction of the producer gas, the said passage terminating in a tubular .projection or a nipple 6. Upon the section 1 anotherl cylindrical part 8 is mounted which is upwardly enlarged, forming the section 9. Within this upper part a shaft 10 is mounted in the bearings 11 and 12 'and provided with a pulley 13. vUpon this shaft 10 vanes 14 are mounted adapted to be moved within the grate shaped members 15. Thesegrate shaped parts 15 are provided with projections 16r opposite to the outer edges of the vanes 14. The grates 15, 16 are secured to the wall of the cylinder 8. Upon ythe shaft 10 the vane shapedy or Ablade-like members 17 are keyed opposite to the ribs 18 which are secured to a bell shaped member 19 whichis open at the top. To the shaft 10 f there are moreover keyed the bell shaped vanes 20, possessing a cylindrical exterior` wall provided with horizontal portions 21 which extend into the close proximity of the .wall 9. -Between the two vanes 2O a bell Shaped member 22 is arranged which is secured to the wall 9. At 23 a sprinkler or shower device is provided, and 24 is a discharge pipe for the water introduced thereby into the apparatus. 25 is the delivery pipe for the tar which may be closed by a stop cock 26, and 27 is the discharge tube for 'p "/,o ribs` 16 of the grate.

By means of the wall 29 it is deilected downwards, until it arrivesl upon the lowest rib 30. Through these ribs or between them and the outer cylindrical wall the gas will then flow upwards. The ribs 31, 32, 33 are so arranged that at those points where one of the ribs is provided with orifices or ports an uninterrupted surface exist inthe following rib, so that by this means also the gas is compelled to change its direction continuously.
